Water is probably the most researched substance on Earth. The interest in water, and redominantly in liquid water, is due to its importance on both macro- and microscopic scales. Although people have been trying to understand water for centuries, this ubiquitous liquid is still surrounded by mystery and has never stopped intriguing us. Even nowadays, we are sometimes powerless in front of large floods provoked by tsunamis or hurricanes.

I would like to gratefully acknowledge several people whose contribution was essential for the accomplishment of this thesis. First, I thank my promoter, Douwe Wiersma, for giving me the opportunity to pursue a Ph.D. in his group. Throughout the years, Douwe managed to maintain high standards of research and I always felt proud to be part of his team.  The work described in this thesis would not have been possible without the continuous and enthusiastic support of my copromoter, Maxim Pshenichnikov, to which I am greatly indebted. I learned a lot from him, not only about physics but also about how important it is to work in a pleasant and relaxed atmosphere and have a good communication with your colleagues.  I wish to thank the members of the reading committee, Huib Bakker, Paul van Loosdrecht and Peter Vöhringer, for their remarks and suggestions. To Peter Vöhringer, as well as to Jörg Lindner, I am also grateful for our pleasant and fruitful collaboration. I would also like to thank Andrei Tokmakoff for the inspiring discussions that we had at several conferences and during his visits to Groningen. These conversations changed my perspective on research and made my decision to leave academia really difficult. I am deeply indebted to Audrius Pugzlys for introducing me to the fascinating world of ultrafast lasers. Probably the most regretted post-doc from Groningen after his departure to Vienna, Audrius was a great friend and an expert always ready to help in the lab. I wish to thank Thomas la Cour Jansen for his contribution to this thesis and for his patience in explaining me theoretical approaches and computational methods. During these years, I really enjoyed the company of our group members, with whom I shared not only scientific insights, but also the pleasure of winning a football tournament. From my very first day in this group, Ralph Hania has been a wonderful colleague and friend, always ready to answer even the most foolish questions. Ralph, thank you for your help and for explaining me so many things about the Dutch culture and society.  I wish to thank Sergiy Yeremenko for sharing his knowledge about our laser system, for his contribution to Chapter 2 of this thesis and for his professional advices regarding hanging wall paper and laying carpet. I am also grateful to Kees Lazonder for his clever tips, to Victor Krasnikov for insightful comments, and to Nibu George for his optimistic attitude which often saved the day.   Acknowledgements  152I thank Maaike Milder for the pleasant time that we spent together studying reverse micelles and for her enthusiastic help during the flooding of the labs from Friday 13th (August, 2004). I also wish to thank Artem Bakulin for his input to Chapter 5 and I express my regret for the glasses that he lost in the Isar River during our swimming contest. The experiments presented in this thesis could not have been realized without the outstanding data collection and processing software created by Foppe de Haan. Owing to Foppe’s proactive and forthcoming attitude, our short brainstorming sessions always lead to a practical solution. Thanks to Ben Hesp, I benefited from an excellent technical support in respect to all kinds of issues, ranging from the design of a new cryostat to locating the reset button of our most expensive laser when it was hanging in error mode. Laura and Dima, my dear paranymphs, with you by my side I am sure that the defense ceremony is going to be fun. Laura, I know that I could not possibly thank you enough for al the things you have done for me, but I am sure that you know how much your friendship means to me. Dima, thank you for all the memorable outings and for all the nice people that you introduced me to.  Living in Groningen would not have been so pleasant without my great friends Szili, Mirko and Mishu. Many thanks to Mirko for his thorough “studies” that he generously shared with me, to Misu for keeping close in this pursuit from the first day, when we met in front of the Dutch embassy, and to Szili for enlightening me on some profound aspects of Romanian language. I wish to thank Silviu for never letting me down when I needed something. He helped me relocating so many times that by now he probably knows my furniture better than I do. I enjoyed many parties, barbeques and outings together with my Romanian friends from Groningen, Alex, Csaba, Magda, Nicoleta, Cristina, Robert, Mirela, Dana, Adi, Ramona, Lacramioara, Vali, Gabi B., Irina C., Aurora, Mihai M., Oana, Odi. I believe that in every physicist’s life there is a moment when an outstanding teacher made a difference and set him on the course of his future career. Personally, I owe a great debt of gratitude to Bianka and Ion Bebu and I wish to thank them for the time and passion that they invested in me. Dear Irina, you are the only person who knows what this job represented for me. With you I shared all the satisfactions and failures of the last years. Thank you for always being there for me! Last but not least, I wish to thank my beloved family for their unconditional support.
